Uur invention relates lothfit class of renrerentin'g tire from entering a building from Without and which are usually constructed "with wire-glass set in metallic or tireproof rsvfing'ing or pivoted sashes; and our inveninprored construction Aoi' fireproof windowof The described character which when closed lljith these ends in View our invent-ion conconstrnetion, combination, angl arrangement of parts by which the said objects and certain other objects hereinafter appearing are attained, all as fully described with reference iculnziy pointed out in the claims. l

In the said drawings, Figure l is a front elevation of a fireproot window constructed according to our improvements. Figi. is a scale, showing the upper sash open in dotted lines, the lot'ver sash being broken away. Fig. 3 vertical sectional view taken on the lino 3 3, Fig. 1, intermediate parts being le a plan section taken on the irregular seclinnlinc 4 4, Fig. 1. Fig. 5 is a perspective rief-v of parts of thev sash and fra-me at the pivotal point on the right-hand side, and Fig.

The window-sill, or, more properly speak, Eng, th at part of the window-fram1 upon which the sill is formed,I is composed'of a single piece of metal, as shown at the bottom of having along its top an upward,- box-shaped bend Il', V,which forms the abutment-flange for the loner edge of the lower glass 2, 3 represen ting the putty or other substance for holdlaeld by. any suitable. clips or other suitable deviees well known, but not shown. The

upper edge of thc lower glass 2 is sented against a [lange or .shoulder l, formed on the division-bar, which extends across the vrinl. dow-frame and is secured at its opposite ends in any suitable way to the upright; members' of such frame. This division-bar is pre-ferably composed of two pieces of sheet. metal, as better `shown in Fig. Il, which at its intermediate part is bent flown to forni theflauge, while its two edges are turned outwardly to form lateral flanges 5 L 'lhe upper side of the division-bar is composed of a single piece of metal whose edges are lapped'over and around the flanges 5 (i. as shown ai 7, and on one side is. carried upwardlyin a vertical di rectiou, andi heu downwardly aud bent upon itself to forni an upwardly-extcnding llauge 8, and s then carried horizontally, as shown at 9, to Form the top of the division bar. This horizontal portion 9 is bent back under itself totvard the left, thence downwardly,

and again toward the right to form a flange l0, projecting laterally along one edge of the division-bnr, such flange 10 heilig considerably above the portion Il, so as to constitute a groove or socket. for the reception of n flange or lip l2, formed on n hood lil, carried bythe lower side of the upper sash, which latter isv pivoted by pivots 14 to the side members of the window-frame, as will be presently described. The lower rne'mberof the upper vslash is preferably com posed of a single piece of sheet metal whose one edge ,is bent. laterally to enter into the formation ofthe flange 1;? and thence upwardly pastthe flange 10, then horizontally across the top 9 of the divsion-bar thon upwardly and downwardly to forml a stilleuinglange 15, which abuts against. the flange S when the upper sash is 4closed and forms therewith a tight joint. From this flange l5 the metal is carried hori- Azontally. and thence upwardly to form a boxshaped flange 16, which constitutes the abutmentlange for the lower edge of the glass 17 o f the upper sash, 18 being the putt-y on the other side of the glans. From thehun-shaped flange 16 the metal is carried downwardly under the lower edge of the glass 17 andv thence horizontedly along itself, downwardly around the llange 10, and nallylappcd over y ber, it being provided with a hood 19, which extends from the pivot 14 down to the bottom member of the sash and is joined in anysuitable. way with the hood 13 and provided with an inwardly-turned ange 2 0 on one side and the stiteninsfflange 21 on the other, as well as with theglass abutmentfflange 22, all of whit-hpa1t-s are'coustituted and formed in the manner before described with reference to the bottom member of the upper sash in Fig. 3. This flange 2O of the side member of the sash interlaps with a flange S33, secured to the side member of the window-frame, which is depressed, as clearly shown in Fig. 4, to formv with the flange 23 a'chamber or recess 21 for the reception of the flange 20', thus making a'tight sill for preventing the admission of tire and water. Asa conveuient and elcient means of attaching the ilange 23 to the side member of the wiudowframe we form such side member with a vertical socket 25 by bending the metal of which the side member is constituted inwardly toward the wall and thence outwardly upon itself, so as to form one long,r lap 26 and a short lap 27 and constituting a narrow socket site direction.

in which an angle 2S, formed on the flange 23, is inserted, the angle 2Q going, preferably, to the inner end of Athe socket 2T, and thus gaging the position of the flange 23.

The sd'e members of the window-frame are the same on both sides and constructed in the manner already described from top to bottom or at least throughout the height of the pivoted sash; but the side members of the pivoted sash from the pivct 14 upward are constructed in the manner shown at the top of Fig. 4, it being understood that the hood and Flange before described for constit-uting the sill along the vertical edges must be so arranged that below the pivot the hood moves outwardly or away from the flange,

` while above the pivot the flange moves away from the hood, and hence in one instance the hood is secured to the window-frame and in the other to the sash. It will also be appreciated that in one inst-ance the sash moves in one direction and in the other in the oppo- Hence the sash from the pivot upward is formed on one side, and the same side as the hood 19, with a straight flange 29, which engages in a hood 30, secured to the side of the window-frame. This hood 30 is formed of a strip of metal bent in the shape of a double l., one flange 3l of which enters the vertical socket 27, formed in the side member of the window-frame, as already described.

The side member of the sash from the pivot the bolts.

14 upward is formed with the flanges 2l 2:?,

as before described; but its edges, instead of' being bent to form three sides of a square, as before described with reference to the lower portion of Fig". 4, are carried out straight. to form the flange 29, and thence lapped one aouud the other, as clearly shown in Fig. 4, to bind the edges together.

The pieces constituting the flange 23 and the hood 30 may be in two parts, if desired, and the edges of the angle-pieces :28.31 allowed to abut one upon the other in the sockets 27.

From the foregoing it. will be understood that the side members of the pivotal sash are i the samerin consti-notion and operation on both sides, but different above and below the pivotal point, as illustratedi in Fig. 4.

The pivots 14 are preferably iu the form of holts,which are passed through the side members of the pivotal sash at a point above its center, so that the lower part of the sash will be the heavier and exert a normal tendency to close when released. It will also be clearly shown from Figs. 3 and 4 that the pivots il are arranged to one eide of the central line ot the side mem hess of the sash. T his is done for the purpose of reducing the arc described by the outer sides of the hoods 1.0, adjacent to the pi vor-al point, and thereby cnabling ns.to project a lap 19 up under the hood 30, secured to the frame, land to bring the end of such hood down closer to the pivot and at the same time maintain the maximum swing or opening of the pivotal sash, a result which could not be accomplished excepting in the minimum degree were the pivot 14 located at the mid-transverse section of the sash members.

The pivot-bolts 14 pass through both sides of the hoods 19 at their upper endsfbut, as shown in Fig. 3, the upper cuds of the tongues or flanges 23 terminate alittle below'the pivot 14, so as not to interfere with the insertionof The inner ends of the bolts pass through the members of the window-frame and may be secured in any suitable manner, as by a threaded block or uut- 32, secured in the side member of the frame; also, if desired, the outer side's of the hoods 19 may he stitfened or reinforced by blocks 22, riveted or otherwise secured thereto.

The top horizontal member 34 of the window-frame may be exactly the same iu construction and design as the side members, excepting that it has the cornice-pieces 35jon each face or side which projects up past the masonry; but it is provided with asocket 27', like the sockets 27 in the side members, and in the socket 20 engages a tongue or flange 36, by means of which a hood 30, exactly the same in construction and arrangement as the hood 30, before described, is secured and supported on the frame and serves for the recep tion of a tongue or flange 29'", formed along one side' of the upper horizontal' member of the pivotal sash. By this means it will be -ioc 'nog

seen that :t perfectsill is also esf-alilsltod alongr the top of the pivotal sash. This top horizontal member-of the pivotal sash ispref erablj: formed of a single strip of', metal u 'liich has one told benl. do\vn\\ardl\ to form the .Jlass:ibutmentflangel? anfldsthen benl out 'nardly and upwardly to form a flange 3S, which overlaps the top horizontal memberof The window-f ame. The stripis thenearrieddownwardly along itself to the o'pposite side of the sash and finally bent around its other edge, as shown at i, to secure the edles to .:ether and at the same time form the flangeor tongue 2D,

"to represents a vertical division-bar, which may be used when the glass'employed is composed of a. plurality of panes. This divisionliar 4t2 connects the lower member ofthe plv om] sash with its uppermember, and a similar baz,- may also be employed in the lower fixed sash, if desired; but in the example shown in the d rawings such bar is'onlit-ted, a single pane hein;y employed in t-helower part of the window. This bar 40 consists of a sin :le strip of metal bent toy form a box-like body portion 4l, which is st-fened by a flange 42, the edges of the strip being carried together between the panes 17 and one edge being,r lapped baci; upon the other, as shown at 43, to tor i a flange for the putty 44.

The pivotal window-sash may be held in its open posit-ion in the usual or any snitable way--snch, for instance, as by means of a rod 45. attached at itsV upper end tothe bolt 46 of a latch ,which secu rcs the windowwheu closed, while the lower end ofthe rod may be securedA to a hook 47 for holding the sash open.
